Quite often, it is tough to picture the difference between sensor sizing just by reviewing a spec sheet. The graphic below may provide you a better sense of the sensor dimensions in the GH5S and K20D.

As you can see, both of these cameras enjoy different resolutions and different sensor sizing. The GH5S having a tinier sensor is going to make getting bokeh trickier and the Pentax K20D will offer you greater detail using its extra 5MP. Greater resolution will help you crop pics far more aggressively. The more recent GH5S provides a benefit with regard to sensor innovation.
